Abstract

Dans cet article, nous étudions la capacité des indices traditionnels de Competitive Balance à correctement mesurer l'attractivité des ligues de sports professionnels, en différenciant les ligues fermées des ligues avec promotion et relégation. Sur la base d'un dispositif original de construction de configurations hypothétiques de classements finaux des clubs, nous mettons en évidence l'inaptitude des indices traditionnels, et en particulier de l'indice de Gini, à rendre compte de l'attractivité des différentes ligues. En nous inscrivant dans la démarche se fondant sur le " parallèle " entre modèles de décision dans le risque et mesure des inégalités (à la suite de Yaari [1987]), nous proposons alors une généralisation de l'indice de Gini permettant de convenablement mesurer l'attractivité des différents types de ligues.
